To escalate a complaint with United Airlines, you should start by contacting their customer service through their official channels, such as phone, email, or the online contact form. Clearly explain your issue, provide all necessary information including your flight number, booking reference, travel dates, and any supporting documentation like receipts or photos. If the issue is not resolved to your satisfaction at this level, you can escalate your complaint by submitting a formal request through United Airlines’ feedback page or by writing a detailed letter to their corporate office. In your escalation, be specific about the problem, explain how it impacted you, and state the resolution you are seeking.

If United Airlines still does not provide a satisfactory response, you can take further steps by filing a complaint with the U.S. Department of Transportation (DOT), which oversees airline consumer issues. The DOT allows passengers to submit complaints online, and these are forwarded to the airline for review and resolution. You may also consider reaching out through social media platforms, as many companies respond more quickly to public posts. Remaining calm, professional, and persistent throughout the process will increase your chances of receiving a meaningful response and resolving your issue with United Airlines effectively.
